Worldwide scientific efforts on nursing in the field of SARS-CoV-2: a cross-sectional survey analysis.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been a global public health issue. This study aimed to characterize global nursing research on SARS-CoV-2. Nursing-related publications through December 31, 2022, were identified using Scopus. The number of studies, study types, countries, institutions, journals, authors, h-index, total confirmed cases, total deaths, and the highest-cited studies were investigated. In total, 12,427 studies were identified. The number of studies increased rapidly, particularly between 2020 and 2021, with a 2.36-fold increase. The United States published the most studies (3,289, 26.47%), followed by the United Kingdom (1,059, 8.52%) and China (877, 7.06%). Scientific productivity significantly correlated with the total confirmed cases (r = 0.701, p = 0.024) and total deaths (r = 0.804, p = 0.005). The United States had the highest h-index (80), followed by China (59), and the United Kingdom (57). The University of Toronto published the most studies (181), followed by Harvard Medical School (165), and the University of São Paulo (107). Gravenstein S (23) was the most prolific author, followed by Mor V (22), and Rosa WE (19). The International Journal of Environmental Research and Public Health published the most papers (436), followed by PLOS ONE (219), and BMJ Open (185). Several countries, institutions, journals, and authors contributed greatly to SARS-CoV-2-related nursing studies. Countries with larger numbers of confirmed cases and deaths tended to publish more nursing studies. The United States, United Kingdom, and China had the highest quantity and quality of studies.

Bibliometric analysis of the global research status and trends of mechanotransduction in cancer.

The development of cancer is thought to involve the dynamic crosstalk between the tumor cells and the microenvironment they inhabit. Such crosstalk is thought to involve mechanotransduction, a process whereby the cells sense mechanical cues such as stiffness, and translate these into biochemical signals, which have an impact on the subsequent cellular activities. Bibliometric analysis is a statistical method that involves investigating different aspects (including authors' names and affiliations, article keywords, journals and citations) of large volumes of literature. Despite an increase in mechanotransduction-related research in recent years, there are currently no bibliometric studies that describe the global status and trends of mechanotransduction-related research in the cancer field. To investigate the global research status and trends of mechanotransduction in cancer from a bibliometric viewpoint. Literature on mechanotransduction in cancer published from January 1, 1900 to December 31, 2022 was retrieved from the Web of Science Core Collection. Excel and GraphPad software carried out the statistical analysis of the relevant author, journal, organization, and country information. The co-authorship, keyword co-occurrence, and keyword burst analysis were visualized with VOSviewer and CiteSpace. Of 597 publications from 745 institutions in 45 countries were published in 268 journals with 35510 citation times. With 270 articles, the United States is a well-established global leader in this field, and the University of California system, the most productive (n = 36) and influential institution (n = 4705 citations), is the most highly active in collaborating with other organizations. Cancers was the most frequent publisher with the highest H-index. The most productive researcher was Valerie M. Weaver, with 10 publications. The combined analysis of concurrent and burst keywords revealed that the future research hotspots of mechanotransduction in cancer were related to the plasma membrane, autophagy, piezo1/2, heterogeneity, cancer diagnosis, and post-transcriptional modifications. Mechanotransduction-related cancer research remains a hot topic. The United States is in the leading position of global research on mechano-oncology after almost 30 years of investigations. Research group cooperations exist but remain largely domestic, lacking cross-national communications. The next big topic in this field is to explore how the plasma membrane and its localized mechanosensor can transduce mechanical force through post-transcriptional modifications and thereby participate in cellular activity regulations and cancer development.

In recent years, the role of ferroptosis in Parkinson's disease (PD) has become a research hotspot based on evidence of abnormal iron deposition and lipid peroxidation damage in the brains of PD patients. This study aims to examine the relevant research on ferroptosis and PD from a bibliometric perspective. Original research and review articles related to ferroptosis and PD were retrieved from the Web of Science Core Collection (WOSCC) database. Statistical analysis and visualization of information including countries, institutions, authors, journals, and keywords of the included studies were conducted using the R software package "bibliometrix." A total of 414 articles met the inclusion criteria, averaging 37.86 citations per article. From 2012 to 2022, the average annual growth rate of research in this area was 63.44%. The corresponding authors of published articles were mainly affiliated with institutions in China, the United States, and Australia. Shanghai Jiao Tong University in China and the University of Melbourne in Australia emerged as the most active and influential institutions. The journal with the highest H-index and publication output was Free Radical Biology and Medicine. "Ferroptosis," "immunotherapy," "prognosis" and "microenvironment" were identified as high-frequency keywords, indicating current and future research directions in this field. This bibliometric study provides insights into current research hotspots and emerging trends in the growing field of ferroptosis research related to PD. The high-frequency keywords identified highlight active areas of investigation involving methods, mechanisms, and populations of interest.

Racial and ethnic diversity of National Comprehensive Cancer Network (NCCN) committee members.

81 Background: Racial and ethnic disparities are pervasive in cancer care including within the workforce and in leadership. A diverse workforce can increase patient satisfaction, treatment adherence, and improve optimal care in underserved populations. NCCN committees set the standard of care for cancer diagnosis, treatment, and survivorship, but little is known about the diversity of committee members. Methods: All NCCN organ-specific treatment guidelines from 2022 were reviewed; demographics including degree and leadership role were documented. Photographs were collected via online search and race, ethnicity, and gender were determined using a combination of facial recognition software and manual review. Academic rank and H-index were collected from professional profiles and Scopus, respectively. Multivariate analysis (MVA) assessed diversity of committees of the deadliest cancers in Black and Hispanic patients (breast, cervical, colon, gastric, gastrointestinal, hepatobiliary, multiple myeloma, non-small cell lung, pancreatic, prostate, rectal, small cell lung, and uterine cancers). Results: 1,172 unique members were found, representing 62 NCCN committees (median: 33.5 members; range: 24-40). Photographs could not be identified for 3, leaving 1,169 as the final sample. NCCN members were 74% White, 24% Asian, 2% Black, and 3% Hispanic. Members were mostly male (62%) and senior faculty (71%). Women were more likely to be junior faculty (25% vs 37% men, p<0.001) with lower median H-Index (20 vs 30 men, p<0.001). Less than half of committees (42%) had at least 1 Black member; most (76%) had at least 1 Hispanic member. The majority (82%) had at least 1 Black or Hispanic member. Of 63 Chairs, most were White (81%) and the remainder were Asian (19%). Of 59 Vice Chairs, 80% were White, 14% were Asian, and 7% were Black. There were no identified Hispanic committee Chairs or Vice Chairs. Committees for the deadliest cancers in Black and Hispanic patients were no more likely to have a respective Black (OR=1.25, 95%CI 0.58-2.71, p=NS) or Hispanic (OR=1.08, 95%CI 0.59-1.97, p=NS) committee member. On MVA, being female (OR=1.27; 95%CI: 1.01-1.58; p=0.038) and having a higher H-index (16-30: OR=1.41; 95%CI: 1.03-1.94; p=0.033; >30: OR=1.83; 95%CI: 1.32-2.55; p<0.001) were associated with increased odds of serving on a committee of a cancer deadliest in Black and Hispanic patients; neither race nor ethnicity increased the odds of serving on these committees. Conclusions: NCCN committee members in 2022 were predominantly White and Asian, with few Chair positions held by Black or Hispanic members. Less than half of committees had any Black member and committees providing guidelines for cancers with high mortality rates in Black and Hispanic patients were no more likely to have diverse members. Future efforts should focus on both diversifying the physician workforce and within leadership positions in oncology.

Polyphenylene sulfide (PPS) with unique performance advantages and development potential is widely used in electronics, aerospace, environmental protection, automobile, machinery, textile, chemical, pharmacy, environmental protection and other industries. The researches on PPS material are constantly advancing and improving in both quantity and quality. To clarify the progress and status, and to explore current focus and development trend of PPS at a global level, the bibliometric analysis was used based on Web of Science Core Collection database. 1118 papers were retrieved, and countries or regions, institutions, journals, authors, research areas, author keywords, and highly cited articles were discussed in detail. The results of bibliometric analysis show that China was the dominant country in terms of contributions of paper output, followed by the USA, South Korea, Japan, India, and Germany. Germany and China both were the most active partner which worked with other high productive countries. “Polymer science” was the most attractive research area with 451 papers involved in. “Journal of Applied Polymer Science” was the most comprehensive source of PPS material publications and with the highest h-index. The author keywords “mechanical property”, “behavior”, “composite”, “morphology”, “kinetics”, “friction”, “tribological property” and “crystallization” reflected a high level attention and hot topics for PPS. Based on the results of bibliometric analysis, the research progress and achievements of preparation, performance improvement and application field expansion in recent years were summarized and explained. To achieve more comprehensive performance and to be suitable for more special applications in various fields, the enhancement and toughening of PPS, the modification by blending or alloying with other polymers or other reinforcing materials, the production of PPS ultrafine fiber and PPS membrane were shownas the research emphasis.

The expansion of team size in library and information science (LIS): Is bigger always better?

The increasing prevalence of large research teams in contemporary science has prompted an investigation into the trends of team size in library and information science (LIS). In this study, we analysed 103,299 LIS publications written by 129,560 unique authors between 2000 and 2020 sourced from the Microsoft Academic Graph (MAG) data sets. We conducted a temporal analysis from multiple dimensions, including journal quartiles, research topics and researchers with varying impact levels. In addition, we employed two multivariate linear regression models – with and without author fixed effects – to scrutinise the relationship between team size and publication impact. Our findings reveal continuous growth in LIS team size. Notably, publications in higher-quartile journals tend to have larger teams; the team size of technical topic publications is generally larger than that of theoretical topic publications; and researchers with a higher h-index are able to assemble larger teams. Although we observed that co-authored papers have a higher average citation impact than single-authored papers, the overall positive impact of team expansion on citation growth is not always significant within the common LIS team size range (three to six authors). Our research suggests that indiscriminately increasing the size of a team may not be a prudent decision.

Trends in research of exosomes associated with breast cancer over the past decade: a scientometric analysis.

Breast cancer remains a significant global health challenge, accounting for 2.3 million new cases in 2020 and ranking as the most prevalent cancer by incidence and the fourth in cancer-related mortality worldwide. In China, breast cancer also rapidly increases incidence and burden. The research of exosomes in breast cancer has attracted more and more attention and has a rapid development. Recognizing the pivotal role of exosomes in breast cancer research, we have undertaken a comprehensive scientometric analysis of pertinent scholarly articles published over the past decade to elucidate the current research landscape for researchers. In this study, we gathered all pertinent publications from the Web of Science. Biblioshiny (a web interface for Bibliometrix), VOSviewer software, and CiteSpace software were used to analyze the information on publications, including global trends, countries, institutions, journals, authors, keywords, and citations. A total of 1,239 articles and 625 review articles were retrieved. The annual global publication output has an increased trend in recent decades overall. China contributed the most articles. The publications of the USA had the most total link strength. Nanjing Medical University had the most total link strength. The most relevant source was the International Journal of Molecular Sciences. Tang JH contributed the most articles and had the highest H-index, G-index, and total link strength. The most cited document was "Tumor exosome integrins determine organotropic metastasis", with 2730 citations. The basic themes included "exosomes", "expression", "cells", "identification", "biomarkers", and "serum". The keyword "membrane vesicle" had the strongest bursts. The keywords "target", "biology", "suppressor cell", "molecular mechanism", "tumor progression", "inhibitor", and "model" appeared as prominent focal points in current research and active areas of exploration. Over the past decade, exosome research in breast cancer has undergone a discernible evolution, shifting from broader investigations of exosome roles to focused exploration of specific pathways relevant to breast cancer. Notably, the emphasis has extended to the clinical application of exosomes as biomarkers and potential therapeutic agents in breast cancer treatment.

Orthopaedic surgery academic productivity - how do we measure up?

Research is vital for evidence-based surgery. Understanding scientometric differences among surgical specialties has scope to inform discussions within and across surgical specialities to develop and maintain a culture of research productivity. This study aims to quantify Australian orthopaedic surgical academic productivity compared to the other specialties within the Royal Australasian College of Surgeons' (RACS). A list of Australian surgeons registered with RACS was compiled using the "find a surgeon" function on the RACS Web site. This list was cross-referenced with the specialty databases on their respective websites. A name search of the SCOPUS database for each individual surgeon was performed. For each individual h-index, m-index, total active publishing years, total publications, and total citations were collected. Orthopaedic surgeons had the equal lowest h-index median 2 (interquartile range:3), the shortest duration involved in research median 5years (14), produced the fewest articles median 2 (7) and attained the second lowest number of citations median 28 (116) of the Australian surgical specialties. When the 10 individuals with highest h-index are compared among specialties, orthopaedic surgeons rank second with a median of 37 (6.5). Our objective data provides a factual comparison and baseline assessment of one aspect of research productivity. It can challenge currently held perceptions of performance and can inform conversations about strategic development. We recommend this assessment to other international Colleges and Societies on regular basis. These accurate academic productivity metrics provide opportunity for developing and maintaining a culture of sustained, significant contribution to surgical research.

Cross-sectional Evaluation of Neurotology Fellowship Directors: A Present-day Snapshot of Leadership.

To identify demographic, training, and career trends of neurotology fellowship directors (FDs). Cross-sectional study. United States. All 26 neurotology FDs identified using the American Neurotology Society (ANS) ACGME Accredited Neurotology Fellowship Program Directory, accessed November 2021. Data were collected via CVs, institutional biographies, and emailed questionnaires. Data collected includes age, gender, race and ethnicity, residency and fellowship training institution, time since training completion until FD, length of time as FD, and Hirsch-index (h-index). Twenty-six FDs were identified, and 17/26 (65.4%) FDs responded to the questionnaire. The majority (23/26; 88.5%) were male. The mean age of male and female FDs was 56 versus 47 years, respectively. Of the 17 that responded to the survey, 82.4% (14/17) self-identified as Caucasian. The mean h-index was 25.4. Older age correlated with a higher h-index (r = 0.46, P = 0.019). The duration (mean ± SD, years) from fellowship graduation to FD appointment was 10.7 ± 8.1 and 6.3 ± 4.8 from institutional hire. Six (23.1%) FDs had secondary graduate degrees, and 9 (34.6%) held a leadership position at a national otolaryngology organization. This observational study assesses demographic data on current neurotology FDs in the United States with an analysis of gender disparities. The objective measures identified can provide a baseline for growth in FD leadership.

Global trends of targeted therapy for hepatocellular carcinoma: A bibliometric and visualized study from 2008 to 2022.

Hepatocellular carcinoma (HCC) is an exceedingly prevalent malignancy with an exceptionally poor prognosis. Targeted therapy is an effective treatment option for patients with advanced HCC. However, there have been no bibliometric analyses of targeted therapies for HCC. This study aimed to assess the current status and future directions of targeted therapy for HCC to provide future scholars with clearer research contents and popular themes. Methods: Literature on targeted therapy for HCC from 2008 to 2022 was obtained from the Web of Science (WoS) and assessed using bibliometric methodology. Additionally, the VOS viewer was applied in the visualization study to conduct bibliographic coupling, co-authorship, co-citation, and co-occurrence analyses of publications. A total of 10,779 papers were subsequently selected. Over the past 15 years, there has been a progressive increase in the number of publications on an annualized basis. China released the most publications in the field, whereas the United States had the highest H-index. Cancers published the most papers. Fudan University had the greatest sway in this area. Studies could be divided into 5 clusters: "Gene and expression research," "Mechanism study," "Nanoparticle study," "Targeted drug research," and "Clinical study." In the upcoming years, more papers on targeted therapy for HCC are expected to be released, demonstrating the potential for this topic to flourish. Particularly, "Clinical study" is the following trendy topic in this field. Other research subfields may likewise exhibit a continuous tendency towards balanced development.

Bibliometric analysis of the global publication activity in the field of relapsing polychondritis during 1960-2023.

Relapsing polychondritis (RP) is an inflammatory disease with significant individual heterogeneity that involves systemic cartilage tissues. This study aimed to perform a bibliometric analysis of RP-related publications to quantitatively assess the scholarly productivity in the field. We extracted the RP-related original research articles and reviews published during 1960-2023 from the Web of Science database by using the keyword "relapsing polychondritis." By using R, CiteSpace, VOSviewer, and SCImago Graphica, the bibliometric analysis was performed on the retrieved publications. A total of 1096 articles, consisting of 909 original research articles and 187 reviews, were identified. A mean annual growth rate of 6.71% was found in the number of RP-related publications during 1960-2022. The United States accounted for the highest number of publications (21.9%), exhibited the highest mean citation number per publication (40.7), and engaged in the most frequent academic collaboration. Three clusters of RP-related journals were identified: 1) otology, rhinology, and laryngology; 2) respiratory and radiology medicine; and 3) rheumatology. Journals with a focus on rheumatology issued the most publications, and most of the RP-related publications were from The Journal of Rheumatology (n = 27). Most of these publications were co-authored by Dr. Jean-Charles Piette (n = 19), who also had the highest H-index (13) among all the authors. The co-citation network analysis revealed 11 highly connected clusters of RP research and indicated the "VEXAS Syndrome" as a hotspot. This overview of the RP research field comprehensively describes the progress in the field. The number of publications on RP has progressively increased but remains insufficient. The United States and European countries are at the forefront of RP-related research, and the journals related to rheumatology have covered the majority of publications. Additionally, several key topics for future investigations, such as "VEXAS Syndrome," have been identified. Key Points •We identified a mean annual growth rate of 6.71% in the number of the RP-related publications during 1960-2022. •The United States accounted for the majority of the publications, exhibited the highest mean citation number per publication, and engaged in the most frequent academic collaborations. •The journals of the publications were categorized into three clusters of research areas: 1) otology, rhinology, and laryngology; 2) respiratory and radiology medicine; and 3) rheumatology.

Analysis of Publication Productivity and Academic Rank of Ophthalmology Residency Program Directors in the United States.

Female ophthalmologists are underrepresented in the field of ophthalmology. This study aimed to analyze the gender differences among ophthalmology residency program directors (PDs) in the United States with respect to academic rank, number of publications, and h-index. This cross-sectional study evaluated 120 ophthalmology residency PDs from 120 ophthalmology residency programs during the 2022 San Francisco Match. The gender information was collected from institutional websites. The information regarding the state of each institute, academic rank, degree (MD or DO), age, and publication productivity was also recorded. From the 120 residency programs, 120 ophthalmology residency PDs were identified. Most PDs had an MD degree (118 out of 120, 98.3%), while only a few had a DO degree (2 out of 120, 1.7%). Only 31 (25.8%) out of 120 residency PDs were female. There was a statistically significant difference between female residency PDs and male residency PDs (p<0.0001). Male PDs had a higher h-index (15.2 ±1.2) compared to their female counterparts (11.9 ± 0.97) (p=0.003). Regarding academic rank, male PD number was higher in each category, including assistant professor, associate professor, and full professor. United States ophthalmology residency programs have a smaller portion of females compared to male PDs. Furthermore, full professors are more likely to be male, and males have higher publication productivity in terms of h-index.To promote equality among ophthalmologists, future initiatives should focus on addressing the gender disparities in ophthalmology residency programs and the selection of residency PDs.

Global research trends on maternal separation paradigms as an early life stress model: A bibliometric analysis

BackgroundMaternal separation (MS) is an early life stress model that is often studied to determine how early life stress affects brain development and psychopathological adaptation. As society has developed, public health problems have become increasingly prominent, and this research area has attracted significant attention. However, to date, there has been no systematic bibliometric study on MS. The aim of this study was to analyze the trends and frontiers in MS using bibliometrics and provide a scientific reference to researchers in the field. MethodsUtilizing VOSviewer, CiteSpace, and Microsoft Excel, examined data obtained from the WoSCC, which encompasses the years 2002–2021. ResultsIn this bibliometric study, we analyzed 6209 articles related to MS authored by 24,174 researchers across 121 countries and regions and published in 2219 journals. The United States had the most publications (2,232, 35.95%) and both the United States and the United Kingdom had the highest h-index. Institutions in the United States and France had the most published articles and citations. Keyword clustering analysis revealed associations between MS and adverse early life experiences, the hypothalamic–pituitary–adrenal (HPA) axis, stress, gene expression, and depression. ConclusionsThis bibliometric analysis highlights the current research focus on the long-term effects of MS on emotional cognition, the HPA axis, epigenetic changes, and their links to gut microbiome imbalances. Future research may expand on these findings to investigate the underlying mechanisms and broader health and societal implications of MS. These results provide a comprehensive overview of the current research landscape in MS and offer valuable insights for researchers to guide future investigations in this field.

Industry Payments and Academic Influence in Reconstructive Microsurgery

Abstract Background Financial relationships between industry and microsurgeons help facilitate innovation but have the potential to bias a surgeon's academic work. To better understand industry–academic relationships, this study investigated the association between industry payments made to microsurgeons and their academic influence. Methods A cross-sectional analysis of microsurgeons at Accreditation Council for Graduate Medical Education–accredited plastic surgery residency programs during the 2020–2021 academic year was performed. The Center for Medicare and Medicaid Services' Open Payments Database was used to collect industry payments (research and nonresearch related) to each surgeon. Academic influence was measured by Hirsch index (h-index) and number of publications. Mann–Whitney's U and Kruskal–Wallis' tests were used for statistical analysis. Results Of the 199 microsurgeons identified, 156 (78.39%) received an industry nonresearch payment, but 0 (0.0%) received an industry research payment. Surgeons who received any amount of industry payments did not have a higher mean h-index or higher mean number of publications than surgeons with no industry payments. However, surgeons with total industry payments more than $10,000 (n = 15) had a higher number of publications than surgeons with no industry payments (135.47 vs. 36.02, p = 0.0074), $1 to $1,000 in payments (135.47 vs. 34.37, p = 0.0006), and $1,000 to $10,000 in payments (135.47 vs. 45.43, p = 0.0268). Surgeons with total industry payments more than $10,000 also had higher h-indices than surgeons with $1 to $1,000 in payments (24.4 vs. 10.34, p = 0.0039) and $1,000 to $10,000 in payments (24.4 vs. 11.34, p = 0.0413). Conclusion Industry funding is associated with higher h-index and higher number of publications for high earners (&gt; $10,000). Private companies may favor these surgeons for their academic expertise.

A Bibliometric Analysis of Mesenchymal Stem Cell-Derived Exosomes in Acute Lung Injury/Acute Respiratory Distress Syndrome from 2013 to 2022.

Mesenchymal stem cell-derived exosomes (MSC-exosomes) have been found to effectively improve the systemic inflammatory response caused by acute lung injury and acute respiratory distress syndrome (ALI/ARDS), regulate systemic immune disorders, and help injured cells repair. The purpose of this study was to take a holistic view of the current status and trends of MSC-exosomes research in ALI/ARDS. Bibliometrix, Citespace and VOSviewer software were used for bibliometric analysis of the data. We analysed the world trends, country distribution, institution contribution, most relevant journals and authors, research hotspots, and research hotspots related to Coronavirus Disease 2019 (COVID-19) based on the data collected. China possessed the largest number of publications, while the USA had the highest H-index and the number of citations. Both China and the USA had a high influence in this research field. The largest number of publications in the field of MSC-exosomes and ALI/ARDS were mainly from the University of California system. Stem Cell Research & Therapy published the largest number of papers in this scope. The author with the greatest contribution was LEE JW, and ZHU YG published an article in Stem Cell with the highest local citation score. The most frequent keyword and the latest research hotspot were "NF-κB" and "Coronavirus Disease 2019". Furthermore, our bibliometric analysis results demonstrated that MSC-exosomes intervention and treatment can effectively alleviate the inflammatory response caused by ALI/ARDS. Our bibliometric study suggested the USA and China have a strong influence in this field. COVID-19-induced ALI/ARDS had become a hot topic of research.
